To all whom may concern Be it known that we, JOSEPH AMA'rrHEws, EDWARDW. FREEMAN, and WILLIAM H. S.

BATEMAN, citizens of the United States, re-

siding at Philadelphia,

in the county of Philadelphia and State of Pennsylvania,

have invented new and useful Improvements in Sash Construction,

of which the follow'- ing is a specification.

An object .of the invention is to provide a sash construction forproviding an effective' weathering contact to prevent the intrusion ofthe elements at the points of engagement of the sash with the frame whenthe sash is closed.

The invention contemplates, among other features, the provision of asash arid frame which, when the sash is closed, presents an effectivejoint or seal against the weather without in any manner preventing 'thelswinging of the sash from a closed to an open position and wherein,furthermore',

.the closing of the sash on the rframe is limited by the construction ofthe. sash and frame along their contacting edges.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views, and in which z. f

Figure 1 is a fragmentary front elevation of thesash and frame; Fig. 2is a vertical sectional view taken on the line 2 2 in Fig. 1; Fig. 3 isan enlarged fragmentary vertical sectionalview taken on the line 3 3 inFig. 1, showing the hinge supporting the sash upon the frame; Fig. 4 isa fragmentary enlarged horizontal sectional view taken on the line 4 4in Fig. l.; Fig. 5 is a fragmentary enlarged horizontal sectional viewtaken on the` line 5 5 in Fig. 1; Fig. 6 is a fragmentary enlargedvertical sectional view taken on the line 6 6 in Fig. 1; and 7 is afragmentary enlarged vertical sectional view takenon the line 7 7 inFig. 1.

Referring more particularly to the views, we disclose a frame 10 and asash 11, said frame 10 having Sides 12 in the nature of verticalT-shaped strips and top -and bottom horizontal strips 13 forming asubstanprojecting web 19, a member 20,

tially-rectangular opening 14 in which the l particularly, and bottom ofconnection of the sash with the frame being preferably called up' persash portions and those portions of the sides lying below the points ofpivotal connectionof the 'sash with the frame being preferably calledlower sash portions. So, also, the portions of the sides ofthe frameabovevthe hinges are preferably called upper frame portions and thoseportions below the hinges, lower frame portions.

Referring to Figs. 1 and 4, it will be seen that the lower portion ofthesash 11 swings forwardly, thus causing the upper portion to-swingrearwardly, and to this end the lower sashv portions, ablyv indicated bythe numeral 17, have riveted or otherwise 'secured to a rearwardly saidmember being secured to the inner side of the web andbearing against ahead 21 forming a part of the lower sash portion. The member 20 issubstantially L shape and secured to the inner side of a web 22 forminga part of-the lower fra-me portion providing a head 23, is a step-shapedmember 24, which has` its outer face of a configuration substantiallysimilar yto the configuration of the member 20, said member 24 alsohaving a projecting portion 25 thereof lapping over the rear end of theweb 19 of the lower sash portion so that when the sash is closed rela--tively to the frame the member'20 will bear against and it into themember 24 and the projection 25 of the member 24 will extend across theinner end of the web 19, thus providing similar adjacent weatheringcontacts at the points where the corners of the ..-member 20 and acorner o'f the web 19 will and which are preferof the sides lying andshown in Fig. 4, and it will be clearly seen by referring to Fig. 4 thatthe arrow indicates the direction in which the sash is adapted to beswung in order to disengage.

the lower sash portion relatively to th'e lower frame portion.

The upper sash portion indicated by the numeral 17b is similar in everyrespect and constitutes a continuation of the lower' sash portion 17,the said upper sash portion 17", however, having riveted or otherwisesecured thereto a member 27 of step-shape.4

Thus it will be seen that the only diii'erence between the upper sashand frame portion and the lower sash and frame portion is that themembers which are secured respectively to the lower frame portions arereverse in their position of the upper sash and frame sections, thearrow in Fig. 5 clearly indicating that the upper sash portion swingsrearwardly whereas, as has been mentioned heretofore and clearlyindicated in Fig. 4 by the arrow, the lower sash portion swingsforwardly or outwardly from the frame.

In Figs. 6 and 7 we disclose in detail the construction of the top andbottom strips 13 and 18 of the respective frame and sash portions. Thebottom strip 18 of the 'lower sash portion is formed to provide adepending ledge or plate 29 and the lower or bottom strip 13 of theframe portion is adapted to provide a head 30, a horizontal angularmember of a substantially Tshape,and indicated by the numeral 31, beingriveted or otherwise secured to the lower or bottom strip 13 of thevframe and fitted therein so that upon closing the sash the dependingplate 29 of the bottom strip 18 will bear against the front edges of thehead 30 and member 31 on the bottom strip of the frame, thus preventingthe intrusion of the elements from the outside of the sash and frame tothe inside thereof, it being further seen that the inner end of thebottom strip 18 of the sash bears against an inner face of the member 31when the sash is swung into a closed position, said inner face of themember 31 being at all times held rigidly against the inner end of thelower strip 13 of the frame, as will be clearly seen by referring toFig. 6.

l In Fig. 7 we disclose the construction of the top strips 13 and 18 ofthe frame and sash, and in this instance it will be seen that the web bya suit-j lthe top strip 13 is formed with ahead 32 and the lower strip18 with a`head 33. Y

Riveted or otherwise secured to the top strip 13 and bearing against aninner face of the head is la member 34 similar in construction andconfiguration to the members 20 and 28 of the lower sash and frameportion described heretofore, a member 35.. being riveted or otherwisesecured to the top strip 18 or' the sash and bearing against an inner"face of the head 33, said member being similar in construction andconfiguration to the members 424 and 27, clearly shown 1n Figs. 4 and 5.To this end, the member 35 is at all times rigid on the strip 18 and has.a projection 36. bearing agalnst theinner 4end of the strip 18 andanother projectlon 37 adapted to bear against the inner end of the strip13 when the sash is in closed posi-- tion, thus forming a series ofweathering contacts indicated by the letters a', b' c and d land whichprevent the intrusion of theV elements at the juncture of the upperportion of the sash with the upper portion of the frame.

From the foregoing description it will thus be seen that in each of theinstances described the sash, when closedupon the frame,

will so have its edges disposed with respect to the edges of theframe'that the resulting joints will prevent intrusion of the elementsfrom the exterior to the interior of the lframe and sash, theyweathering contacts being such that rain, windand snow or sleet cannotenter at the juncture of the respective portions of the sash and frame,this being due to the fact that portions of the sash, ywhen the same isclosed upon the frame, willoverlap portions of the frame, as mentionedAand described, a-nd thus not only afford effective joints but also limitthe closing movement of the sash upon the frame.

Referring to Fig. 5, it will be seen that the weather contacts providedby the juncture of the frame portions with-the sash portions areindicated by the letters a2, b2, c2 and d2, such weather contacts beingsubstantially as effective as those shown in the .construction in Fig.4. With so effectual sealing means between the sash and frame, it willbe clearly apparent that when the sash is closed the intrusion of theelements at the juncture of the sash and frame will be effectuallyprevented.

Having thus described our invention, We claim ln combination with aframe having -T- shaped side strips and top and bottom strips forminganopening, a sash having T- sash, a lstep-shaped member also secured toIn testimony whereof We aix our signathe opposed faces of the webs ofthe T- tures in presence of. two witnesses.
